Getting more bang for your buck is the driving force behind the thriving industry of cannabis extraction. Extracts like bubble hash, kief, wax, oil, or rosin are created when cannabis plant material is separated from its cannabinoids which are then extracted into more concentrated forms.
These concentrated extracts have many touted benefits including more exact dosing and the ability to zero in on the individual benefits of certain cannabis strains. But how are these extracts created? Here are four popular methods for creating cannabis concentrates.
1. Rosin
The rosin method is gaining in popularity because its process involves only heat and pressure with no additional solvents like butane or ethanol. Rosin can be extracted from cannabis flowers, kief, or hash through a fairly simple mechanical means. Using just a hair straightener and a rosin press filter, rosin is extracted without a complicated scientific process and with no residual solvents.
All that's needed is to apply enough pressure and heat to the plant material so that the resin separates in small drops and forms a translucent and sappy product. In some cases, properly made rosin can raise the potency to as much as 70% of THC.
2. CO2
Another popular extraction method is the CO2 method because it is non-toxic and produces no harmful levels of carbon emissions. Like the rosin method, CO2 extraction requires high pressure and heat to extract the desired cannabinoids from the plant matter. When finely tuned and with highly specialized equipment, this process can also be used to extract multiple compounds from the cannabis plant, though typically they are more viscous products, more likely to be used for vaping rather than dabbing.
3. Butane
Butane Hash Oil is created using the butane method, which can create several different final consistencies of cannabis extract including wax, shatter, oil, honeycomb, etc. Because butane is highly dangerous to work with, this method is typically done in a highly controlled lab environment. Butane is run through the plant matter resulting in the extraction of the desired oils. However, because butane is a solvent, the product must then be purged to remove the solvent, which is accomplished by heating the solution in a vacuum.
4. Ethanol
A fourth extraction method uses ethanol to create cannabis concentrates. The product is soaked in a solution of ethanol until the desired cannabinoids are drawn out of the plant material. Sometimes heat is also applied. The ethanol then evaporates from the product and what's left behind is a tar-like product, typically used orally or topically.
